WASTE-MAKING MACHINE.

Application filed July 31, 1919. Serial No. 314,531.

T 0 all whom 2'25 may concern Be it known that 1, Oscar: JoI-IANsnN, a citizen of the Norwegian Monarchy, and resident of Christiania, Norway, have invented certain new and useful Improvements in aste-Making Machines, of which the following is a specification.

This invention relates to machines for making waste from cotton, cloth, rags or other similar material as clothing, curtain material or the like.

The object of the invention is to provide a machine of the character set forth of simple, novel and practical construction and design. 7

One object of the invention is to provide novel means for picking out the weft of the material after it has been cleaned so as to produce long clean waste.

Another object of the invention is to make the several parts of the machine easily accessible. Still another object of the invention is to provide means for automatically stopping the machine in the event it be comes clogged by the bunching or too heavy feeding of the material.

With the above and other objects in view the invention is embodied in a waste making machine as hereinafter describedand as illustrated in the accompanying drawings, in whicha Figure l is a side view of the machine with parts in section;

Fig. 2 is a plan view of the machine with parts in section and parts broken away;

Fig. 3 is a front view of the machine;

F 4 is a rear view of the machine;

Fig. 5 is an enlarged sectional detail view of the picking elements and associated parts;

Fig. 6 is a plan view development of the picker plate which operates with the picking elements;

- Fig. 7 is a sectional view of the picker plate;

Fig. 8 is a detail view gearing. v

The reference numerals 1 and 2 denote the two side frames of the machine and which form the principal supporting elements thereof. The numeral 3 denotes a large picking drum provided with steel pins 4 of which there are about 6000 placed in staggered relationship as will be understood. Forward of the said drum 1 is located a of parts of the small picking drum 5 provided with about vided with grooves 27.

veying belt 10 and the feed drums 5, 6.

On each side of the machine there is suitably pivoted at a hook 16. The hooks 16 overlap and keep in place a transverse flat bar 17. Springs 18 on bolts 19 which pass through said bar keep the latter up against the hooks 16.

The bolts 19 are carried by arms 20 against which the lower ends of the said springs 18 act. The arms 20 carry a sleeved rod 21. To the latter there are pivoted two presser arms 22, 22 which are kept down upon the upper feed drum 6 by springs 23,

23, acting on said presser arms. Thus, the feed drums are kept together by spring pressure, the lower one being carried by the side frames as will be understood.

To the side frames are secured a transverse bar 24 and in the latter is fastened a picker plate 25, see Fig. 6. The picker plate is bent up over the small picker drum and down between and under the large picker drum. The picker plate is provided with slots 26 through which the pins 50 on the small drum project, while opposite the pins 4 on the large drum, the picker plate is pro- Above the small drum and secured to the arms 20 aforesaid is a picker shield 28 with grooves 29 for the pins 50.

The driving elements are as follows: The shaft 29 of the big picker drum 3 is provided with the usual fast and loose pulleys 30 and 31. 32 is the belt which is shifted by the belt shifter 33 slidably carried by a shaft 34. The belt shifter is operated by a forked arm 35 on a shaft 36 which carries a bevel gear 37' in mesh with a toothed sector 38 on the starting shaft 39 which is provided with an off set or crank 40 adapted to lift the brake lever 41 which carries a weight 42. The brake lever is pivoted at 43 and carries a brake shoe 44 adapted to cooperate with the brake disk 45 fast on the large drum shaft 29.

The starting shaft 39 extends across the machine and carries a handle 47. 48 is a lowered away from the in driving enga spring 59, Fig. clutch lever 57 guide plate for the handle 47. While the machine is running the handle stands in a notched cut out 52 in said guide plate in the position shown in Figs. 1 and 2. When it is desired to stop the machine the handle 47 is thrown to the left in these figures and the starting shaft 39 is thus rotated. This in turn shifts the belt from the fast to the loose pulley 31 through the instrumentality of the members 38, 37, 36, 35 and 33. At the same time, however, the crank a0 is also brake lever, which is thereupon operated by the weight 4-2 to brake the machine. The reverse movement of the handle 47 throws ofli' the brake and puts the belt on the fast pulley.

The small picker drum 5 is driven from the shaft 29 through a reduction train of gearing generally indicated by the numeral 53 inwhich the gear 54: which is loose on the driven shaft 57 drives a tooth 55 carried by a collar 56 slidably mounted on the shaft 57 of the small drum, 5. The collar 56 is mounted on the shaft 57 by a key as shown and the tooth on said collar is held 2. The collar 56 operates a pivoted at 58 and adapted to knock the handle 4L7 out of the notch '52.

The operation is as follows: The material is fed into the machine by the conveying belt 10 and passes in'between the feed rollers 6 and 7 and is caught by the pins 50 in the small picker drum and carried around on said drum and under the picker shield 28 which serves to keep the material on said pins 50' under pressure from the springs 18. The pins 50 in the'small drum act as holding or retarding means on the material which is pickedand made into waste by the pins 4: on the large drum. The pins a grip the material one thread at a time and pull out the weft threads from the warp threads,while the pins 50 retard said pulling action and hold onto the material. The small drum is cleaned by means of pickers 60 mounted below the same. In the event the material should crowd or bunch, the rotation of? the small picker drum will be retarded, this in turn will cause the collar 56 to have a tendency to move slower than the gear and consequently the tooth 55 will be forced out of driving connection with said gear and against the action of the spring 59, the clutch lever will be operated and the handle 47 will be thrown in to stopping position and the machine will automatically stop.

When it is desired to clean the machine or for other reasons, the hooks 16 are swung away from the bar 17 which then is forced up by the springs 18. This relieves the pressure in the arms 20, rod 21 and arm 22, also on the shield 28, after which the latter may be lifted ofi'- and access had to the, small Lpick'er drum.-' Fig. 8 shows a train of gearlimited to the structures gement with the gear 5 1 by a ing for driving the shaft 71 on the feed drum 7 and the shaft 72 of the roller 11 from the shaft 57 of thesmall drum 5.

hile the invention has been illustrated in what is considered its best application, it may have other embodiments without departing from its spirit and is not, therefore,

shown in'the drawings.
